I This invention relates to a deodorizer and it is an object of the invention to provide a device .of this kind wherein the rate of dissemination of odor may be controlled or completely shut off.

Another object of the invention is to provide a device of this kind that can be made of a size whereby the device is particularly desirable for home use.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved deodorizer whereby certain advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure l is a view partly in elevation and partly in section illustrating a deodorizer constructed in accordance with an embodiment of the invention;

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1;

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1;

Figure 4 is an elevational view of the cartridge shell or inner cylinder herein comprised unapplied; and

Figure 5 is an enlarged fragmentary detail sectional view illustrating the mounting of a cap with the outer tubular member.

In the embodiment of theinvention as illustrated in the accompanying drawings, B denotes a tubular cylindrical member open at each end. snugly and rotatably fitting into the opposite end portions of the member B are the caps or plugs C of substantially duplicate construction.

Each of the caps or plugs C comprises a body I which extends 'a material distance within the member B and is held therein by a split washer 2 or the like seating within a continuous groove or channel 3 in the inner face of the member B at a desired distance inwardly of the adjacent open end of the member B. This washer 2 is also received within the continuous groove or channel 3 in the periphery of the body I of the cap or plug C and disposed circumferentially therearound.- The grooves or channels 3 and 4 are in register when the body I of the cap or plug is fully inserted, within an end portion of the tubular member B as determined by contact of the flange 5 with the adjacent end edge of the member B. As herein comprised the flange 5 is integral with the outer end portion of the cap or plug C and extends entirely there- 3 Claims. (Cl. 299-) H around. The flange 5 is also of a size to extend beyond the periphery of the member 3 and the peripheral edge face 6 is provided with the straight knurls to facilitate manual rotation of the cap or plug C within and independently of recesses I, the outer ends of which are adapted to be brought into register with the openings 8 provided in the wall of the member B outwardly of the inner end of the body I of the applied associated cap or plug C. The openings 8 are of a number equal to the number of recesses I and are equi-distantly and circumferentially spaced around the member B. In the present embodiment of the invention the recesses I and openings B are each four in number.

Removably fitting within the body member B is a deodorant cartridge K. This cartridge comprises a cylindrical shell 9 of a length substantially equal to the distance between the inserted ends of the caps or plugs C. The shell 9 throughout the major portion of its length is of a diameter materially less than the diameter of the bore III of the member B. The extremities of the shell 9 are outwardly flared, as at I I, with the outer diameter of each of such portions II substantially the same as the diameter of the bore II) of the member B.

The wall of the member III is foraminous and preferably a screen fabric of desired mesh. The wall of the shell 9 at points spaced therealong has pressed outwardly therefrom the surrounding heads I2 of a size to have close frictional contact with the interior face of the shell 9.

Placed within the shell 9 is a filler I I of cotton or other absorbent material and which filler I4 is saturated, with a desired liquid deodorant.

When the device is not in use, the caps or plugs C are turned sufliciently to bring the recesses I out of register with the openings 8. However, in use the caps or plugs C are turned to bring the recesses 1 into register with the openings 8 so that air may freely circulate through the flller I4 and around the cartridge K. The air as it leaves the member B will carry out the deodorant into the outside atmosphere.

To regulate the deodorizing action, the caps or plugs C will be adjusted as desired to bring the recesses I into any selected relation with openings 8 between fully closed and fully opened position.

From the foregoing description it is thought to be obvious that a deodorizerconstructed in acings, the plugs having side recesses opening through their inner ends into the tubular member and registering with the openings of the" tubular member upon rotation of the plugs, and

a deodorant cartridge within the tubular member between the plugs comprising a tubular fora-m inous shell open at its ends, andan absorbent filler in the shell.

2. A deodorizing device comprising a tubular member open on both ends and having openings in its walls adjacent-to said open ends, plugs rotatably fitting in each of the end portions of the tubular member and extending beyond the-open.--

ings, the plugs having side recesses opening through their inner ends into the tubular member and registering with the openings of the tubular member upon rotation of the" plugs; and a deodorant cartridge within the tubular member between the plugs comprising a tubular foram inous shellopen at its ends, an absorbent filler in the shell, said shell being of a length substantially equal tothe space between the applied plugsand of a diameter through the major portion' of its length less than the diameter of the tubular member, theends of the shell being flared and having frictional engagement with the wall of the bore.

3. A deodorizing device comprising a tubular member open on both ends and having openings in its walls adjacent to said open ends, plugs rotatably fitting in each of the portions of the tubular member and extending beyond the openings, the plugs having side recesses opening through their inner ends into the tubular member and registering with the openings of the tubular member upon rotation of the plugs, and a deodorant cartridge within the tubular member between the plugs' comprising a tubular foraminous shell open at its ends, an absorbent filler in the shell, said shell being of a length substantially equal to the space between the applied plugs and of a diameter through the major portion of its length less than the diameter of the-tubular member, the shell having outpressed encircling beads for contact with the wall of said bore.
